WEDGE FOR JOURNAL-BEARINGS.

Specification of Letters Patent.

Patented Nov. 14, 1916.

Application filed February 16, 1916. Serial No. 78,7 58.

To all whom it may concern Be it known that I, STERLING H. CAMP- BELL, a citizen of the United States of America, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful W'edge for J ournal-Bearings, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a wedge for j ournal bearings, and more particularly to journal bearings of railway cars.

The object of my invention is to provide simple and effective means for removing the wedge from its position in the journal box.

In the accompanying drawings, which illustrate some forms of my wedge made in accordance with my invention with so much of a railway journal hearingas is necessary to describe my invention, Figure 1 is an isometric projection showing my preferred form of wedge; Fig. 2 is a longitudinal section through the forward end of the wedge, the wedge being shown in position in the journal box; Fig. 3 is a front,view of the parts shown in Fig. 2; Fig. 4 is a front view of the wedge, showing a slight modification; Fig. 5 is a section taken on the line 55 of Fig. 4; Fig. 6 is a top plan view of the front end of the wedge shown in Fig. 4:; Fig. 7 is a front view of the wedge showing a still further modification; Fig. 8 is a section taken on the line 88 of Fig. 7 Fig. 9 is a top plan view of the front end of the wedge shown in Fig. 7.

Like marks of reference refer to similar parts in the several views of the drawings.

10 is a railway journal box in which is the end 11 of the axle. The journal box 10 is provided with a bearing face 12 adapted to bear on the top of the wedge. It is also provided with bearing faces 18 for limiting the lateral movement of the wedge, and with dependent flanges 14 for preventing the forward movement of the wedge when it is in its normal position in the box. Only one of the bearings 13 and flanges 14 is shown in Figs. 2 and 3 of the drawings, but it will be understood that one of the bearings and flanges is arranged at each side of the journal box.

Referring first to Figs. 1, 2 and 315 represents a wedge adapted to bear upon the brass 16, which is not shown in detail, as it forms no part of the present invention. The wedge 15 is provided with lateral projections 17, adapted to bear against the bearing faces 18 of the box, and with a forwardly projecting wing 18, which is adapted to cooperate with the flanges 14: to prevent the withdrawal of the wedge when it is in its normal position. The upper face 19 of the Wedge 15 is slightly curved longitudinally, not only to allow it to accommodate itself to the varying positions of the box, but also to assist the removal of the wedge from the box.

In order to provide means for forcing the wedge downwardly so that the wing 18 may pass below the flanges 14 of the box, I provide in the forward end of the wedge a tool-way 20, which tool-way is preferably inclined as best shown in Fig. 1. This toolway extends below the upper face of the wedge so that a tool may be readily inserted between the flanges 14, in order to force the forward end of the wedge downwardly. Said movement of the wedge is facilitated by the curved form of its upper bearing face. In order to draw the wedge forwardly out of the box after it has been forced downwardly, I provide a shoulder 21, which iscentrally located with respect to the toolway 20. It will be evident that after the wedge has been forced downwardly a hook shaped tool may be used to cooperate with the shoulder 21 and draw the wedge forward out of the box.

In Figs. 4, 5 and 6 I have shown a slight modification of my wedge. In this form the wedge is provided with a longitudinally curved upper face 19, as in the previously described form. It is also provided with a tool-way 20. The shoulder 21 is, however, omitted, and, in order to draw the wedge forwardly, the tool-way 20 is extended laterally, as best shown at 22 of Fig. 6, so as to provide a pair of shoulders 28, one arranged at each side of the tool-way 20. k

The operation of this form of wedge is the same as that above described, except that in drawing the wedge out of the box the hook shaped tool cooperates with one or the other of the shoulders 23 at the side of the tool-way 20.

In Figs. 7 8 and 9 I have shown a still further modification of my form of wedge.

In this modification both the shoulders 21 and 23 are omitted, and, in order to draw the wedge forwardly out of the box, I provide the wedge at the rear of the tool-way 20 with a recess 24 forming a shoulder 25 just at the rear of the tool-way 20. In this form of wedge the tool for drawing thewedge forwardly is engaged with a shoulder 25 at the rear of the tool-way 20.

In all of the forms of my wedge it will be evident that a tool can be readily inserted from the front of the box to engage with the inclined tool-way and force the wedge down out of contact with the upper face of the box to allow the wing 18 to-pass below the flanges 14:, after which the tool may be engaged with a shoulder in order to draw the wedge forward out of the box, thus providing an easy and effective method of res moving the wedge from the box.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States is:

1. In a device of the class described, the combination of a wedge and a journal box bearing thereon, said wedge having a toolrecei'ving recess formed in the outer edge of its upper surface, and tool-engaging means adjacent to said recess whereby the wedge may be withdrawn longitudinally from the box.

2. In a device of the class'described, the combination of a journal bearing member,

a wedge, and a journal box'bearing on said wedge, said box being provided witha flange for retaining the wedge against outward movement, and the wedge being provided with means on the outer edge of its upper surface situated back of the line of the flange for moving the wedge to a position to pass said flange.

3. In a device of the class described, the combination of a journal bearing member, a wedge, and a journal box bearing on said wedge, said box being provided with a flange for retaining said wedge against outward movement, and the wedge being provided a with a tool-receiving recess in the outer edge 7 of its upper surface and back ofthe'line of the flange.
